    GM Rotors

    With the introduction of our 20 Amp Extreme HEI Module, MSD needed an HEI rotor that could withstand the high output. The answer was to mold their own HEI rotor. The brass contact is retained with a screw just like the race rotors, so you know that this rotor will take anything.

    Application:
  • GM V8 HEI Distributors
  • MSD Dristributor 121-8365
  • MSD Distributor 121-8362

    MSD distributor caps and rotors are designed with performance in mind and molded from high-quality, voltage-insulating material with terminals that resist carbon tracking. Whenever the distributor cap is changed, you should install a new rotor. Likewise, if you're replacing the rotor, be sure to install a new cap as well. MSD has new kits featuring Rynite injection molded distributor caps and retainers to complete your distributor tune-up. MSD also has Cap-A-Dapts to fit large Ford-style caps onto MSD distributors.
